This data collection provides information on individuals
born in Denmark in 1905 and who were still living in Denmark in 1998.
The overall goal of the study was to establish a
genetic-epidemiological database to shed light on the aging process
among the extremely old. The data focus on their physical and
cognitive functioning. Respondents were asked if they had been
previously diagnosed with diseases such as diabetes, arthritis,
asthma, migraine, cancer, stroke, heart attack, or depression, and if
they were experiencing such ailments as cough, body pains, and bone
fracture and were taking medication for them. Questions probed
respondents' feelings about their health, life, and future. To assess
respondents' general health and functioning, they were asked if they
needed assistance with toileting, bathing, dressing, and mobility
around the house, how often they needed to use the bathroom during the
night, and if they used physical aids such as wheelchair, eyeglasses,
crutches, catheter, or diapers. They were also tested for memory and
cognition, mobility, and vision, speech, hearing, and lung
functioning. Information was also elicited on respondents' mental
state and awareness, energy level, menopause, frequency of visits with
children and family, visits from a nurse, use of home care services,
sleeping patterns, smoking and drinking habits, weight gain or loss,
exercise, social activities, hobbies, reading habits, television
viewing, and recent deaths in the family. Demographic items specify
age, body weight and height, education, and marital status.

Data Types:
survey data

Methodology

Sample:
A total of 2,262 persons born in Denmark in 1905. In cases
where the individual was cognitively or physically impaired a proxy
answered the questions. A home-based two-hour multidimensional
interview, including cognitive and physical performance tests and
collection of DNA, was carried out by lay interviewers.
Population-based registers were used to evaluate how representative
the sample was of the population. The participants were located
through the Danish Central Office of Civil Registration.

Mode of Data Collection:
face-to-face interview

Response Rates:
63 percent
